1. Current 1.1. Regular current The current is described by a profile with specified directions and speeds at different levels. Linear interpolation is used to determine current velocity between points defined in the profile. If the profile does not cover the complete water column the current is assumed to be constant outside the tabulated range. 1.2. Regular current from file The current profile can be specified on a file. The format of the file is ' ----------------------------------------- ' Number of current levels ' ----------------------------------------- NCUR ' ----------------------------------------- ' for all current levels i=1,i=NCUR ' ' zlevel direction current ' ----------------------------------------- CURLEV_i CURDIR_i CURVEL_i .. . CURLEV_NCUR CURDIR_NCUR CURVEL_NCUR ' ----------------------------------------- ' end of file ' ----------------------------------------- where NCUR: integer/character: Number of current levels CURLEV_i: real: Global z-coordinate at current level i, \(\mathrm {[L]}\) CURDIR: real: Current propagation direction at current level i. The angle is measured in degrees from the global X-axis counter-clockwise around the global Z-axis. (seen from above) CURVEL: real: Current velocity at current level i, \(\mathrm {[L/T]}\) Environment Waves
